Zovirax is the brand name for acyclovir, a common antiviral medicine. People use it for cold sores, genital herpes, shingles, and sometimes chickenpox. It helps the body fight the virus and can shorten outbreaks if started early.
Zovirax comes as a cream, oral tablets or liquid, and an IV form for serious cases in hospital. For mild cold sores, the 5% cream is usually applied to the affected area several times a day for a few days. Oral acyclovir is used for more serious or recurring infections. Typical adult regimens vary by condition, so your doctor will pick the dose that fits your situation. In hospital settings, an IV form treats severe infections or patients with weakened immune systems.
Start treatment as soon as you notice symptoms. Antivirals work best when given early. If you wait too long, the benefits drop. If you get recurrent outbreaks, talk to your doctor about suppression therapy—daily pills to reduce flare-ups.
Most people tolerate Zovirax well. Common side effects include nausea, headache, and tiredness. Some people notice dizziness or stomach upset. Less often, it can affect the kidneys, especially if you are dehydrated or already have kidney problems. Rarely, severe confusion or hallucinations occur in older adults or those with kidney disease.
Tell your doctor about other medicines you take. Drugs that affect the kidneys, like certain diuretics or nephrotoxic drugs, can increase risk. Probenecid can raise acyclovir levels. Also mention pregnancy, breastfeeding, and any chronic illnesses—your doctor will weigh risks and benefits.
If you notice reduced urination, severe rash, high fever, or new confusion while on acyclovir, seek medical help right away.
Zovirax normally requires a prescription in most countries. Beware of websites that sell prescription meds without asking for one. If you shop online, pick a pharmacy with clear contact info, visible pharmacist credentials, and verified reviews. Avoid prices that look too good to be true; counterfeit pills are a real risk.
Generic acyclovir is widely available and usually cheaper. Check the packaging for batch numbers and expiry dates when your order arrives. Store tablets at room temperature away from moisture. Creams should be kept sealed and used within the timeframe on the tube once opened.
Want to know if Zovirax is right for you? Talk to your GP or a pharmacist. They can confirm the diagnosis, recommend the proper dose, and point you to safe ways to get the medicine. Quick action and smart choices make treatment work better and keep you safer.
